Abstract
The utility model relates to an unloading tool, in particular to a large-sized pre-tightening dismounting device. The large-sized nut pre-tightening dismounting device comprises a fixed bracket, a bogie, a pressure propeller, an unloading shaft and an unloading tray; the unloading shaft is movably connected with the unloading tray, and the unloading tray is provided with six square holes. The nut can be fixed without utilizing a striking manner, the limitation of the field and the space can be avoided, and the pre-tightening dismounting work can be better completed, and a screw can be well protected. The labor intensity is alleviated, the working efficiency is improved, and the large-sized nut pre-tightening dismounting device is particularly suitable for dismounting a large-sized device nut.
Description
Technical field
The utility model relates to handling instrument, particularly a kind of large-scale nut pretension provision for disengagement.
Background technology
At present, a lot of large industry equipments can use large-scale nut, as smelter is hung nut etc. to converter body, in actual production there is many-sided problem in the above-mentioned large-scale nut of dismounting: 1, pretightning force cannot be confirmed---when large-scale nut is installed, in order to reach the requirement of pretightning force, general adopt jack panel in the mode of knocking, but knock strength cannot detect cause cannot Accurate Determining nut pretightning force, be only to rely on workman's experience to judge, have certain risk.2, operating condition is limited---and because the condition of operation site is limited, can only on narrow space, operate, people's quantity of operation is also restricted, inefficiency.3, labour intensity is large---and operator, in order to realize nut pretension and dismounting, takes the manually mode of knocking to carry out, and labour intensity is large.
Utility model content
The purpose of this utility model be to provide a kind of load and unload convenient, laborsavingly save time, safe and reliable large-scale nut pretension provision for disengagement.
The utility model solves the technical scheme that its technical problem adopts:
The provision for disengagement of a kind of large-scale nut pretension, comprises fixed mount, bogie, pressure propeller, handling axle and handling dish; Between described handling axle and handling dish, be flexibly connected, on handling dish, offer hexagonal hole.
On described handling axle and handling dish, offer pin-and-hole, pin-and-hole connects bearing pin.
On described bearing pin, offer insurance hole, insurance hole connects safety plug.
Described pressure propeller is provided with pressure hose, and pressure hose is connected with oil pump or air pump.
Described pressure propeller is provided with pressure sensor.
The beneficial effects of the utility model are:
1, the utility model comprises fixed mount, bogie, pressure propeller, handling axle and handling dish, and handling dish is directly fastened on nut, by pressure propeller, drives the dismounting of handling dish or early warning nut.Shorten the repair time, improved overhaul efficiency.
2, on handling axle and handling dish, offer pin-and-hole, pin-and-hole connects bearing pin.On described bearing pin, offer insurance hole, insurance hole connects safety plug.Pin-and-hole is connected with bearing pin fast and easy, and safety plug can be protected staff's safety, prevents the phenomenon of the stressed ejection of bearing pin in dismounting or pretension.
3, pressure propeller is provided with pressure hose, and pressure hose is connected with oil pump or air pump, and in use factory, existing oil pump or air pump just can be realized work, do not need to be equipped with separately press device.
4, pressure propeller is provided with pressure sensor, contributes to control nut pretightning force size, meets matching requirements, and staff is easy to operate.
The utility model does not re-use the mode hold-down nut knocking in sum, is not subject to the restriction in place and space, can better complete pretension dismantlement work, and screw rod has been played to good protection.The labour intensity of work reduces, and operating efficiency improves, and is particularly suitable for the dismounting of main equipment nut.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side view of the present utility model.
The specific embodiment
A kind of large-scale nut pretension provision for disengagement as shown in the figure, comprises fixed mount 1, bogie 2, pressure propeller 3, handling axle 4 and handling dish 5; On described handling axle 4 and handling dish 5, offer pin-and-hole 7, pin-and-hole 7 connects that bearing pin 8 makes to load and unload axle 4 and handling dish 5 links together.On handling dish 5, offer hexagonal hole 6.On described bearing pin 8, offer insurance hole 9, insurance hole 9 connects safety plug 10.Described pressure propeller 3 is provided with pressure hose 11, and pressure hose 11 is connected with oil pump or air pump.Described pressure propeller 3 is provided with pressure sensor 12.
During pretension, first according to nut size, select adaptive hexagonal hole 6, the handling dish 5 with hexagonal hole 6 is sleeved on nut, fixed mount 1 is fixedly connected with metope, ground or frame.By bogie 2, adjusting angle aligns the pin-and-hole 7 loading and unloading on axle 4 and handling dish 5, insert bearing pin 8 and safety plug 10 is inserted in insurance hole 9, pressure hose 11 is connected with oil pump or air pump, starting oil pump or air pump drives handling axle 4 to advance along nut pretension direction, handling axle 4 drives handling dish 5 to rotate and then pre-load nut, by pressure sensor 12, check the pressure condition of handling axle 4, guarantee to close oil pump when nut produces enough pretightning forces or air pump completes pretension work.During dismounting, first according to nut size, select adaptive hexagonal hole 6, the handling dish 5 with hexagonal hole 6 is sleeved on nut, fixed mount 1 is fixedly connected with metope, ground or frame.By bogie 2, adjusting angle aligns the pin-and-hole 7 loading and unloading on axle 4 and handling dish 5, insert bearing pin 8 and safety plug 10 is inserted in insurance hole 9, pressure hose 11 is connected with oil pump or air pump, starting oil pump or air pump drives handling axle 4 to advance along nut dismounting direction, when nut loosening can rotate, can close oil pump or air pump, manually back out nut and complete dismantlement work.
